program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Here is how i defined my variables

$SplunkInstallationDir = "C:\Program Files\SplunkUniversalForwarder"

& "$SplunkInstallationDir\bin\splunk" start --accept-license --answer-yes --no-prompt

It works if i run manually only.  

Kindly assist

Hi @lumi,

Although your command should work, you might try:

$SplunkInstallationDir = "C:\Program Files\SplunkUniversalForwarder"
& "$($SplunkInstallationDir)\bin\splunk.exe" start --accept-license --answer-yes --no-prompt

# or

$SplunkExe = "C:\Program Files\SplunkUniversalForwarder\bin\splunk.exe"
& $SplunkExe start --accept-license --answer-yes --no-prompt

To run "splunk start," the account should have Full Control permission on C:\Program Files\SplunkUniversalForwarder and all subdirectories and files. Ideally, the command should be executed by the service account, assuming the forwarder is also configured to run as a service.
